Spiral conveyor for feeding in spikes

The firing concerns spiral conveyors for the aligned Feeding clay spikes to a device with which the spikes are attached, for example, in ice tires for motor vehicles will. A. such a spiral conveyor consists of one the spike receiving pot in which a spiral track is arranged is on which the poured into the pot is irregular oriented spikes migrate upwards when the pot is in a Helical oscillation around. its axis is offset For this purpose, the spiral conveyor bowl can be arranged at an incline distributed on its circumference and connected to a base part Trailing arm springs to be positively driven and to his helical oscillation from an electromagnetic Drive are excited.

desired orientation can be given.

The solution to the task, the spikes on the spiral track to be arranged in series one behind the other is known. For example, you only need to keep the Wendelbahn so narrow that there is only one longitudinally aligned spike at each point can accommodate while sideways-wandering .. spikes again fall back into the pot. Spikes that wander upright are made to fall over by placing an obstacle, So far, however, it has been difficult to orient the spikes in the same way so that they can be inserted into the further processing The spikes reaching the device all come into contact with their head first. These difficulties are especially great when the pot holding the spikes is made of one casting, whose spiral path for the spikes and its alignment devices are essentially already molded in the casting, since the manufacture of the pot as a unitary casting does not allow any shape of the alignment devices. So one has one in such a spiral pot made from a casting as a device for the uniform orientation of the spikes running in the helical path in its direction of extension vertical shaft intended to accommodate the spike shafts, whose mouth width is smaller than the diameter of the spike heads. When the spikes get to the manhole mouth on the spiral track, the spike shafts fall regardless of the orientation of the incoming spikes into the sight and the Spikes hang on their heads one behind the other in the crevice

mouth open. The spikes suspended in the same direction can then be placed in the same orientation on the following Line up the spiral track. However, this arrangement has presented difficulties in practice because the spike shafts below the Spike head are provided with an additional collar and the spike shafts during operation of the spiral conveyor often only partially fall into the shaft, since the head of a spike is on the collar of the preceding spike supports. This often results in operational stoppages. But also In the case of spikes without a collar, it is difficult to ensure an unrestrained passage through the alignment device and, in particular, a to ensure the undisturbed exit of the spikes from the shaft. .- ■■ - ■ ■ "■■■; ..-

Has a spiral conveyor pot made of sheet metal for feeding screws to a screw device one is now already serving for the same orientation of "" screws The shaft is essentially horizontal with only a small amount Arranged downward slope and so a better entry and exit of the screws from this shaft from or to the spiral track achieved.

Spiral conveyor bowl made from a casting for sorting lets use of spikes. The fire looks in detail suggest that the shaft in such a spiral conveyor for spikes is in the case of spiral conveyors for screws known from sheet metal way extends radially with only a slight downward slope outward, wherein the spiral path extends radially extends inside in front of the shaft mouth, and that the shaft wall at the transition of the shaft mouth in the continuing spiral track is formed by a curl projecting radially inward from the pot wall of the spiral conveyor. The spikes always stay with their head on the spiral path, but their shafts wander, partly as a result of heavy, partly as a result Centrifugal force, into the shaft. The spike head is supported on the upper edge of the manhole mouth.

The arrangement of the cam according to the firing allows A practically flawlessly functioning transition of the spikes from the shaft to the continuing spiral track can be achieved. In addition, the eye can be formed in the casting without manufacturing difficulties, it only needs the upper shaft wall is a component manufactured separately from the bowl feeder .zu. A particularly uninhibited one Exit of the spikes from the shaft is guaranteed if the extension of the curl along the helical path is longer than the length of the spike.

The shaft can be in a simple manner in one of the cup wall radially inwardly extending bulge from-

formed sän so that the outer contour of the pot remains unchanged remain. With pots for sorting truck spikes you can see however, because of the great length of these spikes, an outer bulge containing the shaft is expedient.

The manufacture of the spiral conveyor pot from one. The aim of the casting is to manufacture the spiral conveyor as cheaply as possible, in particular with as few operations as possible. After the hiring is. Therefore, it is provided that the anchor bracket for an electromagnet used for the vibration drive is already designed on the casting during manufacture. A particularly flat spiral conveyor can be produced if, according to the innovation, a single electromagnet acting horizontally, expediently a flat magnet is used. Preferably, the magnet engages approximately in the ratio sinoC: 1 radially relative to the central W _e ndelbahnradius inwardly tangentially .to Umfseng added to the pot at this. oC is the angle of inclination of the trailing arm springs in relation to the tertiary. Then the oscillation amplitude of the magnet is exactly as large as with. one

The electromagnet acting vertically on the pot. The way / the Shortening of the lever arm becomes a disadvantage that appears to be present more than outweighed by the advantage that the oscillation side much smaller "ist.as with one on the circumference of the pot magnets arranged in the usual way, in which the large air gap caused by the large oscillation amplitude because of the Magnetic characteristic is disadvantageous. Especially good hold for the anchor is obtained when it is embedded in a recess of the Bokkes, preferably as a lateral recess

is designed so that the anchor both from behind and is supported laterally. ; :

The innovation is shown more schematically in the following Drawings explained in more detail on an exemplary embodiment.

The bowl feeder 1 consists of a stepped shape upwardly widening casting, for example made of cast iron or aluminum, which may be known in the art Way is provided with a hard surface layer. The spiral track 2 runs on the inside of the pot T in a spiral upwards and opens into an outlet part 3 with a Outlet pipe 4. The outlet part 3 can be exchanged and, for example, a transition part to a conveyor rail be a device for attaching spikes in ice tires.

The illustrated spiral conveyor is used in the in Fig.1 The illustrated embodiment is excited by a horizontally arranged magnet 15, the poles of which can be seen at 16 are and its armature 17 by screws. 18 in a lateral Recess of a block 20 is attached. The block 20 is also formed in the casting 1 ″ during manufacture The yoke of the magnet is one on the base part 11 with. Screws 22 screwed-on bracket 23 held. The magnet is in the The manner described at the outset is arranged radially very far inward.

The spikes are initially poured randomly into the spiral conveyor bowl 1 and, when the bowl is excited to vibrate, begin to move up the spiral path 2. So that the spikes do not immediately fall back into the pot, the path "is _{inclined about 5 ° with respect to the horizon-If 1.} Valley falling radially outward. The spikes arriving at the obstacle 25 and which happen to be upright are divided from the obstacle into the interior of the The pot is deflected and falls back over the bevel 26 in the inner wall of the pot into the inner pot. The obstacle 25 is arranged so far above the spiral path that lying spikes can pass, but

only in a single row. This can be seen even more precisely from Figure 3, in which it is shown how a deflected vom.Hinderis 25 Spike 30 over bevel 26; crashes. As can be seen, the spike has a relatively large head 31 and on its Shank 32 has a collar 33. But there are also spikes without Collars for which the novelty because of the created by them unrestrained and simple design of the sorting device also from TTorteil. is, .

The device for Gleickorienti'eren the spikes according to the innovation follows-subsequently and is in one of. the inner wall of the pot 35 radially 'inwardly projecting bulge

As shown in detail in Fig. 2, is, the shafts 32 of the spikes fall into this, - while their heads 31 rest on the spiral track 2 and at the top of the outer edge 43 of the upper cover of the Shaft forming part 5I. The floor. 44 of the shaft is inclined about 10 ° to the horizontal.

If the spikes reach the end of 4g> reach the manhole mouth, hit their shafts 32 on one Cam 47 on, the radial from the pot wall 35 of the spiral conveyor protrudes inwards and is slightly rounded towards the shaft. This has the effect that the spikes line up one behind the other on the continuing spiral track 50 that they all keep walking headfirst. The extension of the

Obvious. can almost all essential parts of the Gate direction for the same orientation of the spikes already in the casting of the spiral conveyor pot be formed. this applies both for the guide surface 37, the bottom 44 of the shaft and the cam 47. Only the upper shaft wall 51 is formed by a component inserted separately in the bowl feeder.

The gate at the exit from the Wendelbahn is still for security reasons a bevel 53 is formed in the inner wall of the pot, the spikes migrating out of the strainer into the pot lets fall back. In addition, an ejector 55 is provided above this bevel, so that there is too much at the output 3 Incoming spikes that build up at this point fall back into the pot. So this arrangement acts like a overflow.
